Table 4:

Aperture correction for Lick/IDS indices measured in our sample. The correction for the molecular indices and for the higher-order Balmer lines is additive while the correction for the atomic indices is multiplicative. The aperture correction was only applied to the Coma galaxies, as it is very small for the other redshifts. The type of correction is indicated in the last column.
